Retro is a contemporary term used to describe things from a bygone era. It is often used in a postive sense, refering to quirky or attractive products that are no longer available.
For example, "Retro fashion" or "Retro Chic" may consist of outdated styles, such as tie-dye shirts from the 1970s, or poodle skirts from the 1950s.
